Since this is perceived by security folks as high risk, I'm posting this in the General Discussion area.

"Consider yourself warned: Today is a very good day to update the version of Java running on your computer. This applies to you whether you run Windows, Mac OS X or Linux. If you?ve noticed your machine suggesting that you update Java, do it right away.
The reason? A scary vulnerability in Java that was detected over the summer, and which Oracle has subsequently fixed, is being exploited by people who create the malware and crimeware that causes so many headaches for home users and corporate IT departments."
This is going on the top of the list for our maintenance this weekend.
